How many A4 sheets can be obtained from one A2 sheet? (We can cut one A2 sheet into 2 A3 sheets)
Yes, 4
A0, A1, A2.... sheet nomenclature are practical examples of ratios. This can be observed from the figure below:
From the above figure, we can see that the sequence goes like this:
A0, A1, A2, A3, A4....
We can get 2 A1 sheets from an A0 sheet.
Likewise,
We can get 2 A3 sheets from one A2 sheet and
2 A4 sheets from one A3 sheet.
Therefore from one A2 sheet we can get 4 A4 sheets.
